I’d try the LTS kernel. Your hardware is well supported and drivers are old enough to be reliable, so I’d think it was something related making the WM crash. Kernel stuff.

I installed the LTS kernel and currently running Linux Mulder 6.1.61-1-lts #1 SMP PREEMPT_DYNAMIC Thu, 02 Nov 2023 12:57:06 +0000 x86_64 GNU/Linux
No change

Dunno then. I’m suspecting it might just be a nasty bug, being Plasma 6 is β. Sorry :woman_shrugging:

OT Comment

p.s. Love the machine name. You woudln’t happen to have a second one named Scully?

I just wiped and installed the latest iso with Plasma 6, all is good now :slight_smile:

Please remember Plasma 6 is still Alpha. You are going to need self-solving skills. I’ve been playing around a bit with [kde-unstable] in Arch. It’s exactly as the repository name implies. Not a whole lot of fun if one actually wants to get anything done on their machine. :wink:
